Illinois teen struggles to manage a life-threatening disease.
18-year-old Julie D'Agostino is starring in hairspray this weekend.
She appears completely normal, until you hear her story.
"I've had to have hospitalizations every three to four months," said D'Agostino.
Born with cystic fibrosis, a potentially deadly lung disease, Julie awaits a lung transplant, but is still singing her heart out.
"Even though my breathing is not good, I love to sing, to show everyone I can do it," she said.
All the oxygen tanks and ivs at home keep her alive.
Her twin Natalie is healthy and stars with her in the musical.
"She conceals her sickness so well. No one knows she's hurting in these plays," Julie's sister, Natalie said.
Strength is this family's story.
Julie and Natalie are just one set of twins, and their older twin brothers hold the same fate.
One is well, one also lives with cystic fibrosis.
This play and the twins' performance are a special stamp on their bond.
"She is a true inspiration to family and friends," said Natalie D'agostino.
And this weekend, all the work and life struggles of this family take center stage.
